Segregation of mixed micelles in the presence of polymers

Abstract

The diffusion behaviour of an aqueous mixture of the sugar-based non-ionic surfactant dodecylmalono-bis-N-methylglucamide DBNMG and the anionic surfactant of similar tail length, sodium dodecyl sulfate SDS, are examined in the presence of 5 mass% gelatin; the results clearly show that there are two types of mixed micelle present in the system arising through competition between gelatin and the non-ionic micelle for the anionic surfactant.
